Question

我希望实现一种条纹功能，显示用户打开应用程序的次数。我希望柜台每天增加一个。如果用户应该跳过一天，请将计数器保存为一种“高分”并重新启动计数器

到目前为止，我已经能够使用以下代码计算应用程序打开的次数：

    if (savedInstanceState == null) {
        //initialize streak counter
        SharedPreferences prefs = getPreferences(Context.MODE_PRIVATE);
        SharedPreferences.Editor editor = prefs.edit();

        streakCount = prefs.getInt("counter", 0);
        streakCount++;
        editor.putInt("counter", streakCount);
        editor.apply();
        Toast.makeText(this, "App Opened Count is: " + streakCount, Toast.LENGTH_SHORT)
                .show();
    }

任何关于如何实现这一点的想法都将受到赞赏。

只需将其用作示例

SharedPreferences sharedPreferences = getSharedPreferences("YOUR PREF KEY", Context.MODE_PRIVATE);
Calendar c = Calendar.getInstance();

        int thisDay = c.get(Calendar.DAY_OF_YEAR); // GET THE CURRENT DAY OF THE YEAR

        int lastDay = sharedPreferences.getInt("YOUR DATE PREF KEY", 0); //If we don't have a saved value, use 0.

        int counterOfConsecutiveDays = sharedPreferences.getInt("YOUR COUNTER PREF KEY", 0); //If we don't have a saved value, use 0.

if(lastDay == thisDay -1){
    // CONSECUTIVE DAYS
    counterOfConsecutiveDays = counterOfConsecutiveDays + 1;

    sharedPreferences.edit.putInt("YOUR DATE PREF KEY", thisDay);

    sharedPreferences.edit.putInt("YOUR COUNTER PREF KEY", counterOfConsecutiveDays).commit;
} else {

    sharedPreferences.edit.putInt("YOUR DATE PREF KEY", thisDay);

    sharedPreferences.edit.putInt("YOUR COUNTER PREF KEY", 1).commit();
}
